We are talking about really evil people. Those who commit really evil things, will surely catch an interest from someone among deities. They can't get redemption, but maybe they can convince a cleric of same evil alignment, to pray and ask some evil deity to give shelter. As long as it's still on the same lower plane, it shouldn't break any Multiverse laws.

Existence in the territory of a specific deity is still not much of a paradise, but still much less horrid then "standard" lower plane. In some cases, even just after rebirth petitioner will be tormentor and not one tormented.
I don't think this is accurate: any worshipper of a deity typically goes to their god's afterlife, not just the "really evil" ones. And, there's absolutely no guarantee that the experience will be any better than the Hells.
